To all whom it may concern:

Be it know! that I, GEORGE A. MEYER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented new and useful Improvements in Dipping-Tanks, of which the following is a specification.

My invention relates to improvements in dipping machines. i

The primary object of my invention is to provide a machine for dipping cross arms, ties and other articles requiring liquid treatment, either for the purpose of impregnating or coating them.

A further object ofjmy invention is to provide a machine of this type so arranged that the weight and buoyancy of the product immersed furnishes power to assist in operating the machine.

A further object of my invention is to provide a machine of this type for dipping articles of different sizes and shapes into a suitable bath, for delivering the same from the bath, and for removing the surplus liquid from the product.

A further objectof my invention is to provide a machine of this type capable of being operated easily and efiiciently and with a minimum of attendants.

Figure 1 shows a side elevation of my nil-j proved dipping machine; Fig. 2 shows an end elevation of the same; Fig. 3 shows a sectional view taken on the line 3-3 of Fig. 2; Fig. 4 shows a sectional view taken on the line 4-4 of Fig. 1; Fig. 5 shows a detail of one of the perforated baskets used in dipping small objects; Fig. 6 shows said baskets in operative positlons; Fig. 7 shows a detail sectional view taken on the line 7-7 of Fig. 6; Fig. 8 shows a detail view of the spring actuated dog for operating the device for governing the movement of the rotatable support. Fig. 9 shows a part of the perforated drainage platform in detail; Fig.10 shows a sectional view of a modified form of my dipping tank for treating small objects of metal and other non-buoyant material; Fig. 11 shows a detail perspective view of one of the baskets used in my modified dipping tank.

Referrin to the accompanying drawings, I have use dicate the frame upon which the semi-cylindrical tank 11 is mounted. The transverse guide bars 12 spaced apart in the tank 11 (shown in Fig 3 and 4) PWYGM the reference numeral 10 to inpossible clogging of products in the longitudinally arranged steamheati'ng ip's'1'3.

The shaft 14-extending through t e center I of theJ tank 11 is rotatably'mount'e'd near its ends on the frame 10. Two wheels 15 withserrated peripheries toform seats 16' are feathered on the shaft 14, and on said wheels are mounted the supporting arms 17, which extend in directions approximately tangent to said wheels. The wheels 15 are parallel and their arms 17 are similarly arranged so that corresponding arms on each wheel form pairs to furnisha rotatable support which receives, dips, and delivers products passlng through the tank 11. 1

The loading platform 18 is hinged to the frame 10 adjacent to the tank 11 to form a tilting support for the products to be treated. The lever 19 on the, lat-form 18 is connected by the link 20 to he bell crank 21 which is mounted on the frame 10. Said bell crank is operatively connected the I rod 22 to the treadle 23 on the frame 10,

and through said connections as shown'in Fig. 4 tllts the loading platform 18 to transfer the product to a pair of arms 17, which by the revolution of the ,wheels 15 are brought into alinement with the platform.

The weight of the product rotates the arms,

18 in a clock-wise direction .as seen in 4, and to govern the rotation of said arms,

I have arranged the pawl 24, slidably mounted on the framelO, to engage the ratchet wheel 25, which is keyed to the shaft the frame 10 is connected by the rod 27 to the. treadle 28 on the frar'ne, and engages the lug 29 on the'pawl 24, to disengage said pawl from the ratchet wheel 25. The arms 9O 14. The bell crank 26 pivotally mountedon 17 are free to rotate when the pawl 24 is In operating, the end of the dog 30 de-.

scribes an arc, and releases the pawl 24, as shown in Fig. 8. The s ring 32 connected at one end to the frame and at the other to the pawl 24, returnstthe Same to its normal position where it again engages the ratchet wheel 25. The return action of the pawl 24 is very rapid, and allows only one pair of arms to pass the position for oadmg. The sprin ,33 in connection wit-h the treadle 28 and ame 10, returns the bell crank 26 to its normal operative position, the beveled side of the dog 30 stri es the lug 29 on the pawl 24, and turns on its pivot against the action of the spring 34 until it passes said lug, when it is again returned by saldsprlng to its normal position. The stop rod 35 pivotally connected to the treadle 28 at one end and slidabl mounted through the staple 36 on the fiame 10 at the other, limits the unnecessary downward movement of the treadle 28. The drainage receptacle 37 signed to fit between the arms 17, each being provided with flanged lugs 41, whichiwhen in position are engaged and secured by the spring actuated catches 43, on the wheels 15. I also use a perforated drainage platform 44 in connection with the perforated baskets, which conforms with and rests on the drainage platform 38, as shown in dotted lines,

a the practical operation of my machine, cross arms or other products are placed on the platform 18, and are transferred to a pair of supporting arms 17 by 0 rating the treadle 23 which tilts the plat orm 18. The treadle 28 is then operated to free the rotatable support which turns by the weight -of the product in the supporting arms, thus placing the next pair of arms in position to receive a load from-the platform 18. Assuming that the arms are loaded to their full capacity, articles which have been immersed and have reached the side of the tank opposite to that on which they were, immersed will be thrown out on the drainage platform by the pair of arms following those on which they were first placed. The above operations are. repeated, the article being passed through the liquid contained in the tank, and delivered to the drainage platform 38 over the drainage receptacle 37 where the surplus liquid is shaken and drained from the product. Assuming that the loads delivered from the platform 18 are equal, the combined weight of the article on the feeding side of the tank will overcome the buoyancy of the immersed article on that side and rotate the support until the first of aid art c es hall have the cent r f the support, when their buoyancyunder the arms in the opposite side will assist in rotating the support. The perforated dipping baskets 40 are mounte on the wheels 15 and the perforated platform 44 is affixed to the-platform 38 when it is desired to treat small objects. The operation, when said perforated baskets and platform are in use, is the same as above described.

In the modified form of my device, I have provided for dipping small objects of greater specific gravity than the liquid. The lids 45 of the baskets when open form hinged loading platforms. On each of said basket lids is a tri bar 46 as shown in Figs. 10 and 11 of the rawings. A horizontally arranged lug 47 is mountedin the path of the trip bars 46 on the bracket 48 which is supported on the frame 10. The spring bars 49 are mounted on the hinged sides of the lids 45 and are provided at their ends "with rollers 50 adapted to engage the guide bars '12, and yieldingly hold the lids 45 in closed positions as they travel through the tank.

The rollers 51 mounted on the main frame 10 support the lids 45 in their open position when they form loading platforms for their respective baskets.

The operation of my modified .form of dipping machine is as follows: Assuming one of the-lids 45 to be open as shown at 52 in Fig. 10 of the drawings, articles to be treated are first placed upon said lid, the

treadle 23 is then operated as above described, and the support is turned to rotate the baskets 40. During said rotation, the rollers 51 close the lid 45 of a filled basket,

and the lug 47 opens the lid of the next suo-,

ceeding basket by engaging the trip bar 46, said lid falling outwardly and being supported by the rollers 51. As the operations are repeated and the rollers 50 pass from engagement with the bars 12, the lids 45 are released and are opened by the weight of the treated articles which fall to the perforated drainage platform where the {surplus liquid is drained therefrom. The loading point being higher than the discharging point, a greater number of baskets are on the loading side of the rotatable support, and furnish power for operating the same.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:
